Kosmos Energy Reports Significant Gas Discovery Offshore Senegal

Kosmos Energy has announced a significant gas discovery offshore Senegal.

The Guembeul-1 exploration well, located in the northern part of the St. Louis Offshore Profond license area in Senegal, encountered 101 meters (331 feet) of net gas pay in two excellent quality reservoirs, including 56 meters (184 feet) in the Lower Cenomanian and 45 meters (148 feet) in the underlying Albian, with no water encountered, the company said Wednesday.

The well is located about 5 km south of the basin-opening Tortue-1 gas discovery (renamed Ahmeyim) in approx. 2,700 meters of water.

Based on the integration of the Guembeul-1 well results, the Pmean gross resource estimate for the Tortue West structure has increased to 11 Tcf from 8 Tcf as a result of greater reservoir (net to gross) confidence in the Cenomanian, as well as the inclusion of volumes in the Albian. Accordingly, the Pmean gross resource estimate for the Greater Tortue Complex has increased to 17 Tcf from 14 Tcf.

Kosmos holds a 60 percent interest in the Guembeul-1 well, along with Timis Corporation at 30 percent and Petrosen at 10 percent. Since 2014, Kosmos has held rights to conduct exploration in the St. Louis Offshore Profond and Cayar Offshore Profond license areas under production sharing contracts with the Government of Senegal.
